| Research Abstract |
In this study, I have tried to develop the method for analyzing DNA sequence of dried fruits, which were treated with sulfites as a preservative.
As a result, in specific dried fruits, it was suggested that some nucleotides were converted to another, and it was not possible to analyze the DNA sequence, although the amount of PCR amplification products was enough to use. Using real time PCR system with SYBR green fluorescent reagent, it was possible to detect dried fruits more clearly than using thermal cycler and electrophoresis, and the real time PCR products were useful for direct sequencing of nucleotides.
